GRAIN-BINDER.

SPECIFICATION forming `part of Letters Patent No. 238,327, dated March 1, 1881.

Application filed April 22, 1880. (No model.)

To `alt whom @traag/.concern Be itknown that I, JOHN AUGsPUReER, a citizen of the United States, residing at Trenton, Butler county, Ohio, have invented new and useful Improvements in GrainBinders, of which the following' is a specification. 1

My invention relatesto that classof knottying devices for binders designed especially for the use of twine in which a tube is employed as a mandrel, around which` the twine is wound to form a loop, through which the ends are drawn by a sliding hook, which forms the knot; and it consists in the combination and arrangement of parts, as hereinafter more fully set forth. Y

`My invention is embodied in mechanism illustrated in the accompanying drawings, in Whichtion with the grain-tableremoved Fig. 2, an enlarged perspective view of the tube and its connecting parts, showing the cordin position during the operation of tying, Fig. 3, a`ver` tical longitudinal section of the tube 5 and Fig. 4, a cross-section of the tube through the internal stops.

Similar letters of reference indicate similar parts throughout the drawings.

A indicates a met-al tube, of suitable size, secured beneath the grain-table in supports attached thereto.

For clearer illustration I have shown the parts supported upon a platform, B, which may or may not be arranged as part of the workin g machine. The supports s s therefor are shown as projecting upward from the platform B. A fixed collar, a., upon the tube A, adjacent to one of the supports, s, prevents the tube from moving outward, while a coiled spring, c, between the collar a and the support s', offers a yielding impediment to its movement in the contrary direction.

Within the tubeAis a bar, D, extending entirely through its len gth,provided at its near end with a square head, d, having a hook, h, at its extremity, which ordinarily projects slightly from the end of the tube A. Within thev tube A, near the end, are secured semi-cylindrical blocks e, between which the squared head d of the bar D has a longitudinal movement. The remote projectingeend of the bar D is squared and embraced in a rectangular aperture at the end of a lever, E, pivoted to the grain-table or to the lower platform, B. Between thelever E and the end of the bar D is a short spiral spring, b, secured against a pin at the end of the bar, for a purpose hereinafter set forth. A spring, f, holds the lever E, and, by consequence, the bar D, ordinarily in such position that the hook h projects fromthe other endof the tube A, as stated; but when thelever is drawn to the right the hook h is .drawn within `the tube A and between the blocks e, for a purpose presently to appear. The connection of the bar D with the lever E, as will be obvious, prevents rotation of the bar D and the squared head dof the bar; and the blocks c of the tube also prevent rotation of the tube,

while a free longitudinal movement of both is Figure 1 is a perspective view of my inven- 1 permitted, except as hereinbefore explained.

The device by` which the cord is looped `over the tube A consists, mainly, of a catch-hook, F,

secured to a short section of tube, Gr, mounted upon the main tube Aand rotating freely about it. The tube G is provided with a sheave or guide-wheel, g, beneath which a lever, H, having a horizontal movement and provided with a tooth, t', entering between the iian ges ofthe guide-wheel g, is arranged to guide and adjust the position ofthe tube G. The catch-hook F is provided with a sliding bar, k, sliding in supports l Z, and ordinarily held in position to cover and close the opening of the hook F by a spiral spring, 7c', secured at one end to the bar lc, and resting against the guide-supports l at the other, so that when the bar is drawn back the resiliency of the spring restores it to the position shown. The remote end of the sliding bar 7c is turned upinto a iin ger, m,which, Whenthe tube G and catch-hook are rotated, engages at the proper time against a suitablydisposed cam-plate, M, projecting below the grain-table, and withdraws the sliding bar 7c, leaving the hook open for a short interval until the cam-plate is passed and the spring k re storesthebartoposition. ThetubeGandcatch hook are rotated by a cog or sprocket wheel, N, which has also a guide groove, a, in which a n ger, uf, secured upon the platform B rests and prevents lateral displacement. The tube G has a free longitudinal movement in the wheel, but is compelled to rotate with it by a IOO feather, O, on the tube and corresponding groove in the wheel.

The operation of my device is as follows: The cord C being looped about the bundle of grain upon the grain-table by the due operation of a needle-bar, its two ends are brought together belowr the tube A, by the end of which the two end sections together pass vertically and are guided into thejaw of the cutting-plate P, where they are held by suitable devices. The catch-hook F' is then caused to rotate in the direction shown by the arrow, Fig. 2. As it nears the cord the finger m engages with the cam-plate M, which draws back the sliding bar 7c, thus opening the hook and allowing the cords to be caught and held after the disengagement of the sliding bar 7c. At -this time, also, the cord is cut at P by suitable devices, and the catch-hook continuingits rotation the. cord is wound entirely around the tube A. After making an entire revolution and passing by the upper portion of the cord, the catch-bar is moved forward by the action of the lever H and guide-finger i, and thus brings the cord across the end of the tube A and the loop formed thereon, and within the projecting hook h, as shown in Fig. 2. At this stage its rotation ceases, and the hook is drawn within the tube by the lever, drawing the ends of the cord with it until its relative movement is stopped by the blocks e, when the tube itself is drawn in the same direction against the force of the spring c. This movement withdraws the tube from the cord looped about it, which thus slips over the end of the tube, and by the continued travel of the rod and tube forms a knot. rlhe spring b at the end of the rod prevents the cord from being cut or injured by the stops e when drawn between them by the hook h. It also allows the end of the cord to disengage itself entirely from the tube and hook. When this is done the parts resume their original position for a repetition of the same movements. v

The driving mechanism by which these movements are produced and the knot-tyin g devices operated havebeen but partiallyindicated herein, it being my intention to describe the same more fully in a separate application for Letters Patent.

Having fully described my invention,I claim and desire to secure by Letters Patentl. The combination of the longitudinallyyielding tubular mandrel A, provided with internal blocks, e, the non-rotating reciprocating rod D, having an angular head, d, guided between said blocks, and provided with the hook h, the rotating and reciprocating sleeve G, provided with the catch-hook F and guides Z, and the reciprocating spring actuated bar 7c, arranged in said guides for opening and closing the catch-hook, all substantially as shown and described.

2. The sleeve G, provided with guide-wheel g, and carrying the catch-hook F, in combination with the feathered drivin g-wheel N, guidewheel a, and guide-tooth fn', substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence ofv two subscribing witnesses.
